Generate videos with Seedance API and poll for completion with bounded retries

## Seedance ### How it works This workflow manually starts a Seedance video generation request, submits the configured prompt and model to a video generation API, then polls for completion. It carries loop state through each wait-and-poll cycle, merges the API response with that state, and routes the result to success, failure, timeout, or another polling iteration. ### Setup steps - Configure the HTTP Request nodes with the required API authentication for the Seedance-compatible video generation service. - Update the setFields node with the desired model, prompt, output size, and base_url. - Adjust intervalSeconds and maxPolls in saveTaskId or related loop-state Set nodes to control polling frequency and timeout behavior. - Run the workflow manually from the manualTrigger node to test the full generation and polling flow. ### Customization Change the prompt, model, size, polling interval, and maximum poll count to match the desired video output and service limits.
